Re: How to Capture a 4 way WPA handshake and Upload it to a Online WPA Cracker

I just thought i would test that service out with my handshake. First time i used a service like this and i was just curious. Not a good result as it came back saying password not found!! i wonder what is the success rate if you dont mind me asking?

Try the wiffy script it gets wpa hanshake every time Great script from g0tmi1k.
You need a good signal - wiffy shows green for good signal but will work for lower signal strength but not when in the red
I have a usb Wifi (zd1211 chip set) stick which works better than my built in atheros.

You must have a pretty good password then.

Of course, if you really wanted to have some fun, go to Wal-Mart late at night and ask the greeter if they could help you find trashbags, roll of carpet, rope, quicklime, clorox and a shovel. See if they give you any strange looks. --Streaker69

Are you sure the handshake was good that you sent to the online cracker.
I have captured what I thought was a handshake from a client that was trying at the time to associate to the AP with the wrong pass phrase.
Then it would not crack. I have not tried the online service but also wondered what the success rate is.

I also uploaded a .cap file that got a no password found response from this site. I later found out that it was because the handshake that I had uploaded was not complete. I sent an email to moxie asking if I could resend a complete handshake but have yet to receive a response. On the other hand question-defense was very prompt and professional in getting back to me and basically gave me the go ahead to resend it when I recover the complete handshake.

I then started to wonder how the hell can I tell if the handshake that I have captured is complete or not before uploading it to one of these sites. Luckily in the faq on wpacracker they mention the aircrack-ng tutorial and wireshark. Wireshark is provided in backtrack or you can also download it for windows. Once you have captured the handshake you can open the .cap file in wireshark and and apply the eapol filter. This will then tell you if your capture contains 0, 1, 2, 3 or 4 eapol packets which I believe are the different parts of the handshake. I have a little more researching to do on this to find out just how many eapol packets a good handshake contains. If anyone could chime in here that would be great.
